Summary: This draft is ready for publication as a BCP.
Major issues:
Minor issues:
Nits/editorial comments:
Two comments:
First, there are good arguments for publication as Informational , but
since it incrementally adds to BCP 72, it should be incorporated
there, so BCP is slightly better.
Second, the only significant difference from -04 was the removal of
"and be prepared to justify their decisions". There was a lot of
discussion that led to this, and some concern that the statement on
architectural considerations is not strongly enough worded without it.
However, see the previous paragraph (both paragraphs are below). I
believe that these two paragraphs, taken together, do what is desired.
Those developing IETF specifications need to be able to describe how
they have considered PM, and, if the attack is relevant to the work
to be published, be able to justify related design decisions. This
does not mean a new "pervasive monitoring considerations" section is
needed in IETF documentation. It means that, if asked, there needs
to be a good answer to the question "is pervasive monitoring relevant
to this work and if so how has it been considered?"
In particular, architectural decisions, including which existing
technology is re-used, may significantly impact the vulnerability of
a protocol to PM. Those developing IETF specifications therefore
need to consider mitigating PM when making these architectural
decisions. Getting adequate, early review of architectural decisions
including whether appropriate mitigation of PM can be made is
important. Revisiting these architectural decisions late in the
process is very costly.
